Field of application of the invention

The invention relates to a combination of exterior wall elements with the supporting skeleton in the corner of buildings and is particularly suitable for single and multi-storey steel and reinforced concrete skeleton constructions. A preferred field of application are plate skeleton constructions, which are based on static systems with spatial support.

Characteristic of bekannton state of the art There are solutions for corner joints in skeleton structures known, but all act rigid. These include connections in which the corner wall elements by means of brackets and steel wedges, which one after attachment with Concrete wrapped, connected to the supporting skeleton. Another possibility is the clamping of the wall elements in the corner of the building with hooked into the corner support Anchor bolts and pressed against the outside of the wall panels steel clamps. According to DE-OS 2357669 and CH-PS 541047 corner joints of wall elements are known in which by special Reinforcement arrangement and introduction of filled concrete and fixed and permanent corner joints are created. there

According to DE-OS 2357669 a square Eckelemont is used and manufactured according to CH-PS 541047 a particularly reinforced square corner in cast-in-situ concrete.

The CH-PS 513301 represents corner solutions for prefabricated houses, in which angle-shaped outer wall corner elements application

find that form a cavity to be filled with in-situ concrete with the end faces of the outer wall panels. In these

Corner elements are anchored during their prefabrication so-called diagonal tension, which in the establishment of the Build a firm bias of the angular corner elements against the adjacent outer wall panels

allow it and deform previously inserted sealing strips so that tight corner joints arise. The solid

Corner joints can be reached here, after solidification of the filling concrete to be introduced. The basic lack of known from the prior art corner joints for buildings from prefabricated Components is that, because of their flexural strength for plate skeleton construction, which static systems with

spatial support are not suitable because they do not allow any shifts of the components and occurring Zwängungskräfto would cause damage to such buildings. The conventional constructions have therefore uneconomically large props, which are to exclude possible displacements. According to the state of the art, the cost for the corresponding foundation solutions is correspondingly high.

It should be noted here on compounds that are on the edge of the relevant state of the art, because they relate to attachments of exterior wall panels or cladding panels to supporting components in the planar area of the facades.

Thus, DE-OS 2009682 discloses a proposal for easy and quick engagement and subsequent setting of

Wall parts in a precisely predetermined position relative to supports, which have at least one opening penetrating them for receiving a bolt, sitting on the building inside a clamping part in a recess of the support, while the other end of the bolt carries a cylindrical or oval disc eccentric, which with a steel support part of the Wall part rotatably connected. This solution is suitable for the attachment of large and heavy wall elements for the production of solid compounds.

Heavy cladding panels can also adjust according to US-PS 3350830 adjust and disassemble by

Steel parts are joined together according to the slot principle. .

A fixing object for the simultaneous recording of temperature differences resulting restraint forces in the facade area includes DE-OS 2547263. This is a - solution with all-round and continuous adjustment for attachment of z. B. facade panels at a certain distance from z. B. supports by means of a retaining screw and so-called anchor rails presented.

These last-mentioned objects of the invention alone also do not permit any complete movement of the entire supporting skeleton, independent of the building envelope construction, in the case of panel skeleton constructions.

Object of the invention

It is the object of the invention to produce buildings in slab skeleton construction more economical than before. In particular, rolled steel and cement are to be saved in order to simultaneously contribute to reducing the consumption of process ore.

Explanation of the essence of the invention

The invention has for its object to find a compound of outer wall elements with the supporting skeleton in the corner of buildings of skeleton construction, which holds the outer wall elements on the supporting skeleton when using static systems with spatial support for skeletal structures, horizontal displacements in two directions between outer wall and columns using known restraining forces compensating compounds in the area of 'facade surfaces over the entire building length and depth allows höhenbeweglir.h and at the same time transmits forces acting perpendicular to the walls in the columns.

According to the invention, this object is achieved in that a support angle, the prii. Jpiell consists of a rectangular, bent sheet steel with holes and two perpendicular to each other, perpendicular to one leg of this bent steel sheet welded steel plates, each with a through hole, is attached to a steel component of the corner support of the building skeleton and pivotally receives anchor bolt, the longitudinal and Hold gable wall elements, wherein the outer wall corner element can rest against this support angle. Each of the two anchor bolts hooked into a steel tab of the support bracket and carries at its other end a pressed against the respective outer wall element clamping bracket. According to a variant of the solution according to the invention, a clamping bolt, which is fixedly mounted on a head end of the outer wall corner element supporting eyelet, engages with its hook-shaped other end in a bore of the support bracket so as to hold the Außenwandeckelement at least one point. The support bracket is supplemented in this case by two mutually perpendicular rectangular steel sheets, which are welded at right angles to its two steel straps. Instead of these steel sheets and an angle section piece can be attached. In the connection variant at the head of the uppermost outer wall corner element of a building is proposed for the production of a solid connection between the outer wall corner element and support bracket to provide on the building inside icke last element above a steel component.

The corner joint according to the invention, with which the goal dor invention is achieved is articulated freely movable in all three planes, thereby occurring in plate-skeletal structures constraining forces from different load cases, including from temperature differences and concrete shrinkage can be included or excluded. This corner joint is loadable immediately after installation.

Most effective is the new corner solution for slab skeletal structures with spatial support, in which all or the r.leisten outer wall panel are fixed by means of articulated or partially compliant connections to the supporting skeleton of the building. Here is a complete independent of the outer wall construction mobility of the entire supporting skeleton of the plate skeleton building is achieved.

embodiments

The invention will be further described by examples below. To show:

The most advantageous realization of the invention takes place in reinforced concrete skeleton construction, where exterior wall elements in the entire area

the façades can be mounted without constraint in the supporting skeleton of the building.

For this attachment of the wall panels of Gebäudelängs- and gable surfaces to supporting components used for example

suitable clamping connections, solutions with against each other vorgesetzt arranged anchor channels, the ball joint principle and also connections with spring elements.

FIG. 1 now shows-far beyond the state of the art-one movable in all three planes

acting corner joint for Plauen reinforced concrete skeleton buildings.

In this case, located in the corner support 1 of the supporting skeleton a steel component 7, through which a support bracket 3 by means of bolts

is firmly mounted on the corner support 1. This support bracket 3 consists of a rectangular, preferably bent by 45 degrees steel sheet as a basic element, which has two holes in each of its legs here in Figure 1. On the building exterior leg of this bent steel sheet is perpendicular on each side of this leg

Steel strap, which is a continuous loc. has, welded (Figures 4 and 5). In each hole hooks an anchor bolt 6, the

at its other threaded end by means of a clamping angle 8, the respective longitudinal · 9 and

Gable wall element 10 anchored. In order to achieve a stable contact pressure of the clamping bracket 8 against the wall elements, is

a hexagon nut 11 counter-screwed.

For aesthetic reasons and to improve the tightness of the building envelope this Klemmwinkelverankerung with Klemmriatten or strips are clad from the outside. In the present hall cover rails are made of galvanized Stab'blech used. Diet e example solution can, inter alia, in the construction of multi-purpose buildings with spatial impact in

the static ratios corresponding distances in the range of the height of an outer wall plate are applied several times. But it is necessary, as Figure 1 also shows that outer wall corner element 2 at one point, preferably at its

To hold the head end, including the support bracket 3 with two mutually perpendicular rectangular steel sheets, the

his two steel straps building exterior welded at right angles, is executed (Figures 2 and 3) and a

Clamping bolt 4, which is provided on a provided at the head end of the outer wall corner element 2 supporting eye 5 by known means

is fixed, engages with its hook in a bore of the support bracket 3.

This second embodiment assumes that the outer wall corner element 2 has a recess at the top, around which To include elements of the clamping bolt anchorage. In a third embodiment, wherein the outer wall corner element 2 is fixedly arranged on the support bracket 3, has

the outer wall corner element 2 at its building inside corner also via a steel mounting part 7, for example a

To be able to produce welded connection. This variant is for static reasons as a corner joint at the top Cancellation possible. The most significant new advantage of the illustrated corner joint is that by their industrial application the

spatial bearing effect of plate skeleton constructions for a high material economy can be exploited in the construction of single and multi-storey buildings. Primarily, there is a significant saving of rolled steel and

Cement, because in particular bearing components get smaller dimensions than in the usual construction methods. In addition, there is the advantage that the multi-purpose building designed and used immediately after assembly

can be, because concrete strengthening processes in comparison with rigid building corners, where the introduction of

Fill concrete is required, omitted.
